Just some of the Vexilar firsts include: the first liquid crystal display, the first fish alarm, the first three color display, and the first CRT and straight line paper graphs for the sport fisherman. 1 GENERAL DESCRIPTION The FL-10 is a compact in-dash mounted flasher fish finder. [. . . ] Try not to change the gain setting as you move around as this will affect the color and width of the mark.

Figure K gives you an idea of what it may look like. To find the bottom in weeds it is important to keep the gain control low. If the gain is too high the bottom and the weeds will "run together" making it difficult to determine the actual depth. Some weed beds can be so dense that they will display as solid color, even at minimum gain. To find depth in these conditions it is often helpful to read the display backwards. In the counter-clockwise direction, look for the bottom by first finding the trailing edge of the signal. Further into it, you'll see the main part of the bottom mark and then the leading edge , as in figure K. If you are in weedy conditions often, you may want to add an S-Cable to your system (see page 23). This cuts down your output power allowing for clearer readings in shallow weedy water. SEEING FISH The FL-10 sees a fish as a target, much like the bottom. It has a leading edge, a width, and color content. This can be due to a poor transducer mounting job or from engine exhaust or trolling motor thrust passing under it. Acoustical noise can be eliminated by adjusting the transducer's location or position. HIGH SPEED OPERATION The FL-10 can accurately read depths at almost any boat speed. Here high speed is defined as any speed at or above the planning speed of the boat. Once the boat starts to plane out, turbulence will develop behind the transom. If you are using the wrong type of transducer, or it is poorly mounted, the unit will lose the bottom at a certain boat speed or fill the display with acoustical noise. This is due to all of the air bubbles in the turbulent water. Make sure you are using the proper transducer for your application and that you follow the mounting instructions carefully.
